getRSSS(ipar, theta_grid, is_minscore_0, prior_mu_sigma)

Arguments

ipar

an item parameter matrix for graded response items. Accepts both a/b and a/d format parameters. Accepts multidimensional item parameters.

theta_grid

the theta grid to use.

is_minscore_0

if TRUE, the scores of each item begins from 0. if FALSE, the scores of each item begins from 1.
